Re: [Boost-users] [graph] Crash in breadth_first_search

First you initialize

Graph g;

Afterward you initialize:

Graph G(5);
//add some vertices and edges

And then you start to work with empty Graph g ;) Sure it will not work!

If you simply remove

Graph g;

compiler will point you what to fix ;)

With Kind Regards,
